This charming infographic portrays the evolution of Black Rock City and Burning Man over the years of its existence. The imagery is sweet and wide-ranging, bringing the history, iconography, and ethos of Burning Man together in a satisfying melange of color and cuteness. The closer you look, the more detail there is to see! The image hosted on the web is in Russian, but there's a downloadable English version as well.
Here is a link to the page translated into English.
Here is a link to download the 7.5mb print resolution image. Note - once you download the file, you may need to rename it (chop off the .pdf at the end, so the filename ends in .jpg) in order for it to work properly on your system.
